Table 1. The known (uppercase) and assigned (lowercase) PUUV status of all bank vole captures on the core grid.
| PUUV antibody/infection status | Number |
|---|---|
| Seronegative; susceptible at t | 1871 |
| SS: negative, captured as negative at t–1 | 1027 |
| MS: negative, captured as positive at t–1 | 78 |
| 0S: assigned by weight as not in population at t–1 | 97 |
| ?S: negative, not captured but assigned by weight as in population at t–1 | 669 |
| sS: assigned as susceptible at t–1 | 555.0 |
| mS: assigned as immune due to maternal antibodies at t–1 | 114.0 |
| Seropositive (P): infected (I/i) or protected by maternal antibodies (M/m) at t | 1415 |
| II: positive, captured as positive at t–1 | 828 |
| SI: positive, captured as negative at t–1 | 223 |
| ?P: positive, not captured at t–1 | 364 |
| 0M: positive year-born, later captured as negative; assigned not in population at t–1 | 47 |
| mM: positive year-born, later captured as negative; assigned as immune at t–1 | 31 |
| 0m: positive year-born, not re-captured as negative; assigned not in population at t–1 | 52 |
| mm: positive year-born, not re-captured as negative; assigned as immune by weight | 49.6 |
| ?i: positive adult, or a year-born assigned as infected by weight | 184.4 |
| ii: assigned as infected and seroconverted before t–1 | 118.2 |
| si: assigned as infected and seroconverted between t–1 and t | 59.1 |
| xi: no data to assign PUUV status for t–1 | 7 |
| Total PUUV infection status | |
| Susceptible (SS + MS + 0 S + ?S) | 1871.0 |
| Infected (II + SI + ?i) | 1235.4 |
| Maternal antibody positive (0M + mM + 0m + mm) | 179.6 |
| Total N of captures | 3286 |
P = seropositive, S/s = susceptible, M/m = maternal antibody positive, I/i = infected, 0 = not in population, ? = unknown, x = undetermined.
Capital letters indicate status deduced from serological history, small letters the assigned status.
In PUUV infection/antibody status, the first character indicates PUUV status at t−1 (previous trapping session), and second character the PUUV status at t (current trapping session).
Seroconversion rates for total population and yearly cohorts per trapping session were calculated from (SI + si)/(SS + SI + ss + si), marked in bold.
